Mpi Load Video
Fast, no-frills video loader: decodes frames + audio and reports source info (fps, frame_count, duration, width, height) in one ffmpeg pass. No in-graph preview and no VHS param surface, so it loads much faster than Load Video (Path). Also outputs has_audio (True when the file contains an audio track). Input is named 'string' to match MpiString / MpiAnyChecker. Empty/missing path blocks downstream unless block_if_empty is off, in which case it outputs a blank 1x1 image + silent audio so the graph continues.
